Explanation:

The UN Security Council has expressed “deep concern" over the “maintenance of peace and security” in Ukraine and backed efforts by Secretary-General Antonio Guterres to find a peaceful solution.

• The UNSC is the body responsible for maintaining international peace and security.
• As per the UN charter's direction, the body can take actions on its behalf with regards to global peace.
• During disputes and threats to international peace and security, the body can ask to probe into issues, ask members to apply economic sanctions and take military action on the aggressor.
• UN peacekeeping operations are one of its major responsibilities.

Composition of UNSC
